Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterFast, Reliable Chimney Cleaning & Sweep Across North Bay Shore
A standard chimney cleaning and sweep in North Bay Shore runs $189 to $329 for a single flue with a standard masonry fireplace, and most jobs are completed in 60 to 90 minutes. If you haven’t had the flue looked at since before your oil-to-gas conversion, or if you’re seeing fine brown dust on the hearth after windy nights, call Wendell and his crew at Top Hat Chimney at (631) 318-8656 and we’ll get you on the schedule.
North Bay Shore homes weren’t built for the heating systems they use now. That’s the short version of why we stay busy here. The Cape Cods and ranches that went up between 1948 and 1972 were framed around big oil-fired boilers and oversized clay flues. When gas came through and the boilers got swapped, a lot of those flues never got downsized or lined. We know the streets out here, from Manatuck Boulevard down to the blocks off Pine Aire Drive, and we know what’s inside those chimneys before we even set the ladder.
Why Top Hat Chimney Is North Bay Shore’s Preferred Chimney Cleaning & Sweep Company
Wendell founded Top Hat Chimney in 1999, and he’s been running a brush through Long Island flues ever since. If you call, a live person answers. It might be Wendell himself. You will not get a phone tree, a call center, or a “service window” that stretches from noon to five. We give you a real arrival time, and if traffic on the Southern State or Sunrise Highway slows the truck down, we call you before you have to wonder where we are.
North Bay Shore customers keep our number because the price we quote on the phone is the price on the invoice. No door-knock upcharges, no “discovered damage” surprises buried in a repair quote. If we find something, we show you the camera footage and explain it in plain English. Our Chimney Cleaning & Sweep team operates the same way everywhere, but around here, that plain-English part matters. A homeowner who just found out their oil-to-gas conversion left them with a code-noncompliant flue shouldn’t have to translate a sales pitch.
Our Chimney Cleaning & Sweep Services in North Bay Shore
Level 1 Inspection
A Level 1 inspection is included with every sweep we do in North Bay Shore. We check the readily accessible portions of the flue, the firebox, the damper, and the cap. For most wood-burning fireplaces in the Cape Cods and ranches out here, that’s the right level. If you use the fireplace occasionally and haven’t noticed anything odd, this is all you need. A Level 1 combined with a cleaning runs $189 to $249 for most North Bay Shore single-flue homes.
Level 2 Inspection
If you just bought a house in North Bay Shore, converted your boiler from oil to gas, or had a chimney fire at some point, you want a Level 2 inspection. We run a camera down the flue and document everything: cracked clay tiles, missing mortar joints, the oversized-flue condition that plagues post-conversion homes along the Great South Bay corridor. This is the inspection that catches the stuff a brush can’t reach. A Level 2 inspection in North Bay Shore runs $349 to $549 depending on flue height and access.
Creosote Removal
Creosote builds differently depending on what you burn and how hot your fires run. Around North Bay Shore, where plenty of people burn unseasoned or salt-dampened wood from backyards and local suppliers, we see heavier glaze than you’d expect inland. First-degree creosote is a brush job. Third-degree is a glaze. Catch it early, and a sweep is all you need. Let it build, and the conversation changes to relining. Creosote removal as part of a sweep runs $189 to $329.
Soot Removal
Soot is what’s left when your fire burns hot and clean, but it still needs to come out. A soot-coated flue restricts draft and sends fine black dust back into the house every time the wind shifts off the bay. In North Bay Shore’s older homes, soot tends to mix with spalled brick fragments from deteriorating crowns, which is a sign we need to look at more than just the flue itself. Soot removal is included in the sweep price and typically adds twenty to thirty minutes to the job.

Trusted Brands We Service in North Bay Shore
The salt air off the Great South Bay is rough on chimney components, so we don’t install bargain parts and pretend they’ll hold up. We work with DuraFlex stainless liners for relining jobs, HeatShield for flue resurfacing when the clay tiles are cracked but the structure is sound, and Copperfield for caps and crowns built to take coastal weather. We keep common parts stocked on the truck, so a North Bay Shore homeowner doesn’t wait a week for a cap replacement that should take an afternoon.
Common Chimney Cleaning & Sweep Problems We See in North Bay Shore Homes
- Oversized flues after oil-to-gas conversion. The original 8-inch clay flue was built to vent a big oil boiler, not a 40,000 BTU gas furnace. The result is chronic backdrafting that pushes exhaust gases into living spaces on cold bay nights. This is the defining chimney condition in North Bay Shore, and it’s usually found by camera, not by eye.
- Spalling brick and crumbling crowns from bay moisture. Persistent humidity off the Great South Bay penetrates old mortar joints, and every freeze-thaw cycle in January and February pops another chunk of brick face. We find brick fragments in fireboxes during sweeps all the time out here, especially on unprotected 1950s-era chimneys.
- Corroded galvanized caps from salt air. Galvanized steel doesn’t last long near the water. North Bay Shore homeowners who picked up a cheap cap at a big-box store ten years ago often have a rusted-out cap letting rain and debris straight down the flue between cleanings.
- Deferred maintenance from decades of ownership turnover. North Bay Shore is a working-class hamlet where houses changed hands a lot. That means chimneys went years or decades without inspection. Many flues we open in North Bay Shore haven’t been looked at since the original boiler was pulled out.

FAQs - Chimney Cleaning & Sweep in North Bay Shore
Once a year, burn or no burn. Homes near the Great South Bay take on more ambient moisture than inland properties, and that moisture mixes with creosote and soot inside the flue to form a thicker, stickier residue. If you’re burning every weekend during the season and you’re close to the water, consider a mid-season check in January. A lot of North Bay Shore chimneys break in the off-season too, so the annual visit catches crown spalling and cap corrosion before they become liners and rebuilds. Call (631) 318-8656 and we’ll schedule your sweep while you’re thinking about it.
Because the crown wasn’t built to shed water in a bay-front climate, and repointing the brick doesn’t fix the crown itself. The real issue is that the original crown on your 1950s Cape was likely poured with a standard mortar mix that absorbs water instead of shedding it. Coastal humidity plus freeze-thaw cycles means that water freezes inside the crown, expands, and cracks it from within. The fix is a proper concrete or steel-reinforced crown with a drip edge, often paired with waterproofing, not another patch job. Most North Bay Shore crown rebuilds we do run $350 to $850. Call (631) 318-8656 for a free assessment.
Because your old 8-inch clay flue is too big for your new gas boiler. The original chimney was sized for an oil-fired boiler that pushed a lot of exhaust up a wide flue. A 40,000 BTU gas furnace produces less heat and less draft, so the exhaust cools too fast and loses its lift. When the wind comes off the Great South Bay, it pushes down through the oversized flue and the combustion gases spill back into the living space. We saw this exact condition on Manatuck Boulevard at a 1958 ranch where the 8-inch clay flue was still venting a 40,000 BTU gas boiler with no liner swap. The homeowner thought they had a drafty living room. A Level 2 camera inspection showed the real problem. We recommended a DuraFlex stainless liner downsized to 5 inches, which corrected the draft and brought the flue to code. Call (631) 318-8656 and we’ll scope yours.
An unlined or mismatched flue left over from an oil-to-gas conversion, followed closely by deteriorated mortar crowns. The oil-to-gas issue is the one that creates real safety problems, because the old clay flue doesn’t match the smaller gas appliance and exhaust backs up into the house. Carbon monoxide is colorless and odorless, and the first sign is often a persistent headache or a faint exhaust smell near the boiler. If your North Bay Shore home was converted before you bought it, schedule a Level 2 inspection. The straightforward annual sweep doesn’t catch what’s happening inside the flue walls. Call (631) 318-8656 to book one.
Yes, without question. Galvanized caps fail fast in salt air. The zinc coating on galvanized steel corrodes within a few years of coastal exposure, and once that coating goes, the steel underneath rusts through and lets rain straight into the flue. A stainless steel cap from Copperfield or a comparable brand lasts decades in North Bay Shore’s bay-front humidity. The price difference is small, usually $50 to $150 depending on size, and it’s far cheaper than the water damage and spalling a failed cap causes over a few winters. Call (631) 318-8656 and we’ll bring a stainless cap on the next visit.
